Estado: ModificadaMedia (4.9)—

Cisco NX-OS on Nexus 7000 series switches does not properly handle certain line-card replacements, which might allow remote authenticated users to cause a denial of service (memory consumption) via a crafted configuration that references interfaces that do not exist on the new card, aka Bug ID CSCud44300.
